Short summary
This study employs the Darcy-Brinkman-Stokes equations to characterize the coupled seepage process in porous media of the karst aquifer and the free flow process in karst conduit and stream. Results show that the impact of different water retention models on the interaction process is quite significant. The degree of change in water level of the stream also varies, and this change can affect the ease with which different strata media in the karst aquifer recharge the stream.
